Transportation from Tolmin (Slovenia) to Wacken

My friend and I are going to Metaldays (Tolmin, Slovenia) and afterwards to Wacken, but we have no transportation nor ideas how to get from Tolmin to Wacken. If anyone is going by car and has room for the two of us, we'll gladly share the costs of the trip.
If anyone has some suggestions as to how to get from one place to another, please share.
